ABSTRACT

Therapeutic methods of treating chronic lymphocytic leukemia (CLL) and small lymphocytic leukemia (SLL) are described. In certain embodiments, the invention includes therapeutic methods of treating CLL and SLL using a BTK inhibitor. In certain embodiments, the invention includes therapeutic methods of treating subtypes of CLL and SLL using a BTK inhibitor, including subtypes of CLL in patients sensitive to thrombosis and subtypes of CLL that increase monocytes and NK cells in peripheral blood after treatment with a BTK inhibitor. In certain embodiments, the invention includes therapeutic methods of treating CLL and SLL using a combination of a BTK inhibitor and an anti-CD20 antibody.

FIELD OF THE INVENTION

Therapeutic methods of treating chronic lymphocytic leukemia using aBruton's tyrosine kinase (BTK) inhibitor are disclosed herein.

BACKGROUND OF THE INVENTION

Bruton's Tyrosine Kinase (BTK or Btk) is a TEC family non-receptorprotein kinase expressed in B cells and myeloid cells. The function ofBTK in signaling pathways activated by the engagement of the B cellreceptor (BCR) and FCER1 on mast cells is well established. Functionalmutations in BTK in humans result in a primary immunodeficiency diseasecharacterized by a defect in B cell development with a block betweenpro- and pre-B cell stages. The result is an almost complete absence ofB lymphocytes, causing a pronounced reduction of serum immunoglobulin ofall classes. These findings support a key role for BTK in the regulationof the production of auto-antibodies in autoimmune diseases.

Other diseases with an important role for dysfunctional B cells are Bcell malignancies. The reported role for BTK in the regulation ofproliferation and apoptosis of B cells indicates the potential for BTKinhibitors in the treatment of B cell lymphomas. BTK inhibitors havethus been developed as potential therapies, as described in O. J. D'Cruzand F. M. Uckun, OncoTargets and Therapy 2013, 6, 161-176.

B cell chronic lymphocytic leukemia (CLL) is one of the most prevalent Bcell malignancies in adults. CLL is characterized by an expansion ofmonoclonal mature B cells. CLL patients who relapsed after standardtreatments generally experience poor outcomes. Although survival hasbeen improved by the addition of immunotherapies such as rituximab tostandard chemotherapies such as fludarabine and cyclophosphamide, asdescribed in M. Hallek, et al., Lancet, 2010, 76, 1164-74, many standardtreatments are associated with toxicities and immunosuppression. Thereis therefore a significant need to identify less toxic and highlyefficacious treatments for CLL. Small lymphocytic leukemia (SLL) isclosely related to CLL, and differs only in that a lower level ofmonoclonal lymphocytes is observed in blood than in CLL, along with anenlarged spleen or lymph nodes. There is also a significant need toidentify less toxic and highly efficacious treatments for SLL.

CLL (and SLL) cells rapidly accumulate and are resistant to apoptosis invivo, but are known to die rapidly in vitro. M. Buchner, et al., Blood2010, 115, 4497-506. One cause of this effect is from nonmalignantaccessory cells in the tumor microenvironment, such as stromal cellcontact mediated cell survival. Stromal cells in the bone marrow andlymph nodes are known to have an antiapoptotic and protective effect onCLL cells, protecting them from both chemotherapeutic and spontaneousapoptosis. R. E. Mudry, et al., Blood 2000, 96, 1926-32. The chemokineSDF1α (CXCL12) directs homing of CLL cells towards protective niches. M.Burger, et al., Blood 2005, 106, 1824-30. Existing drugs that target theBCR pathway in B cell malignancies can lead to some lymphocytosis, i.e.lymphocyte egress from nodal compartments, through disruption ofCXCR4-SDF1α signaling and other adhesion factors in bone marrow and theresulting mobilization of cells. However, existing therapies may noteradicate residual malignent B cell populations in the microenvironmentof the bone marrow and lymph nodes, where protective stromal cellsprevent apoptosis. There is thus an urgent need for treatments thatreduce or overcome the protective effect of the microenvironment on CLLcells to enable superior clinical responses in patients.

“Heterocycloalkyl” refers to a stable 3- to 18-membered non-aromaticring radical that comprises two to twelve carbon atoms and from one tosix heteroatoms selected from nitrogen, oxygen and sulfur. Whenever itappears herein, a numerical range such as “3 to 18” refers to eachinteger in the given range—e.g., “3 to 18 ring atoms” means that theheterocycloalkyl group may consist of 3 ring atoms, 4 ring atoms, etc.,up to and including 18 ring atoms. Unless stated otherwise specificallyin the specification, the heterocycloalkyl radical is a monocyclic,bicyclic, tricyclic or tetracyclic ring system, which may include fusedor bridged ring systems.

“Heterocycloalkyl” also includes bicyclic ring systems wherein onenon-aromatic ring, usually with 3 to 7 ring atoms, contains at least 2carbon atoms in addition to 1-3 heteroatoms independently selected fromoxygen, sulfur, and nitrogen, as well as combinations comprising atleast one of the foregoing heteroatoms; and the other ring, usually with3 to 7 ring atoms, optionally contains 1-3 heteroatoms independentlyselected from oxygen, sulfur, and nitrogen and is not aromatic.

“Isomers” are different compounds that have the same molecular formula.“Stereoisomers” are isomers that differ only in the way the atoms arearranged in space—i.e., having a different stereochemical configuration.“Enantiomers” are a pair of stereoisomers that are non-superimposablemirror images of each other. A 1:1 mixture of a pair of enantiomers is a“racemic” mixture. The term “(±)” is used to designate a racemic mixturewhere appropriate. “Diastereoisomers” are stereoisomers that have atleast two asymmetric atoms, but which are not mirror-images of eachother. The absolute stereochemistry is specified according to theCahn-Ingold-Prelog R—S system. When a compound is a pure enantiomer thestereochemistry at each chiral carbon can be specified by either R or S.Resolved compounds whose absolute configuration is unknown can bedesignated (+) or (−) depending on the direction (dextro- orlevorotatory) which they rotate plane polarized light at the wavelengthof the sodium D line. Certain of the compounds described herein containone or more asymmetric centers and can thus give rise to enantiomers,diastereomers, and other stereoisomeric forms that can be defined, interms of absolute stereochemistry, as (R)- or (S)-. The present chemicalentities, pharmaceutical compositions and methods are meant to includeall such possible isomers, including racemic mixtures, optically pureforms and intermediate mixtures. Optically active (R)- and (S)-isomerscan be prepared using chiral synthons or chiral reagents, or resolvedusing conventional techniques. When the compounds described hereincontain olefinic double bonds or other centers of geometric asymmetry,and unless specified otherwise, it is intended that the compoundsinclude both E and Z geometric isomers.

“Enantiomeric purity” as used herein refers to the relative amounts,expressed as a percentage, of the presence of a specific enantiomerrelative to the other enantiomer. For example, if a compound, which maypotentially have an (R)- or an (S)-isomeric configuration, is present asa racemic mixture, the enantiomeric purity is about 50% with respect toeither the (R)- or (S)-isomer. If that compound has one isomeric formpredominant over the other, for example, 80% (S)- and 20% (R)-, theenantiomeric purity of the compound with respect to the (S)-isomericform is 80%. The enantiomeric purity of a compound can be determined ina number of ways known in the art, including but not limited tochromatography using a chiral support, polarimetric measurement of therotation of polarized light, nuclear magnetic resonance spectroscopyusing chiral shift reagents which include but are not limited tolanthanide containing chiral complexes or the Pirkle alcohol, orderivatization of a compounds using a chiral compound such as Mosher'sacid followed by chromatography or nuclear magnetic resonancespectroscopy.

“Moiety” refers to a specific segment or functional group of a molecule.Chemical moieties are often recognized chemical entities embedded in orappended to a molecule.

“Nitro” refers to the —NO₂ radical.

“Oxa” refers to the —O— radical.

“Oxo” refers to the ═O radical.

“Tautomers” are structurally distinct isomers that interconvert bytautomerization. “Tautomerization” is a form of isomerization andincludes prototropic or proton-shift tautomerization, which isconsidered a subset of acid-base chemistry. “Prototropictautomerization” or “proton-shift tautomerization” involves themigration of a proton accompanied by changes in bond order, often theinterchange of a single bond with an adjacent double bond. Wheretautomerization is possible (e.g. in solution), a chemical equilibriumof tautomers can be reached. An example of tautomerization is keto-enoltautomerization. A specific example of keto-enol tautomerization is theinterconversion of pentane-2,4-dione and 4-hydroxypent-3-en-2-onetautomers. Another example of tautomerization is phenol-ketotautomerization. A specific example of phenol-keto tautomerization isthe interconversion of pyridin-4-ol and pyridin-4(1H)-one tautomers.

The terms “enantiomerically enriched,” “enantiomerically pure,” and“non-racemic,” as used herein, refer to compositions in which thepercent by weight of one enantiomer is greater than the amount of thatone enantiomer in a control mixture of the racemic composition (e.g.,greater than 1:1 by weight). For example, an enantiomerically enrichedpreparation of the (S)-enantiomer, means a preparation of the compoundhaving greater than 50% by weight of the (S)-enantiomer relative to the(R)-enantiomer, such as at least 75% by weight, such as at least 80% byweight. In some embodiments, the enrichment can be significantly greaterthan 80% by weight, providing a “substantially enantiomericallyenriched,” “substantially enantiomerically pure,” or a “substantiallynon-racemic” preparation, which refers to preparations of compositionswhich have at least 85% by weight of one enantiomer relative to theother enantiomer, such as at least 90% by weight, and such as at least95% by weight. The terms “diastereomerically enriched” and“diastereomerically pure,” as used herein, refer to compositions inwhich the percent by weight of one diastereomer is greater than theamount of that one diastereomer in a control mixture of diastereomers.In some embodiments, the enrichment can be significantly greater than80% by weight, providing a “substantially diastereomerically enriched”or “substantially diastereomerically pure” preparation, which refers topreparations of compositions which have at least 85% by weight of onediastereomer relative to other diastereomers, such as at least 90% byweight, and such as at least 95% by weight.

In preferred embodiments, the enantiomerically enriched composition hasa higher potency with respect to therapeutic utility per unit mass thandoes the racemic mixture of that composition. Enantiomers can beisolated from mixtures by methods known to those skilled in the art,including chiral high pressure liquid chromatography (HPLC) and theformation and crystallization of chiral salts; or preferred enantiomerscan be prepared by asymmetric syntheses. See, for example, Jacques, etal., Enantiomers, Racemates and Resolutions, Wiley Interscience, NewYork (1981); E. L. Eliel and S. H. Wilen, Stereochemistry of OrganicCompounds, Wiley-Interscience, New York (1994).

A “leaving group or atom” is any group or atom that will, under selectedreaction conditions, cleave from the starting material, thus promotingreaction at a specified site. Examples of such groups, unless otherwisespecified, include halogen atoms and mesyloxy, p-nitrobenzensulphonyloxyand tosyloxy groups.

“Protecting group” is intended to mean a group that selectively blocksone or more reactive sites in a multifunctional compound such that achemical reaction can be carried out selectively on another unprotectedreactive site and the group can then be readily removed after theselective reaction is complete. A variety of protecting groups aredisclosed, for example, in T. H. Greene and P. G. M. Wuts, ProtectiveGroups in Organic Synthesis, 3^(rd) Ed., John Wiley & Sons, New York(1999).

“Solvate” refers to a compound in physical association with one or moremolecules of a pharmaceutically acceptable solvent.

Thesubstituents themselves may be substituted, for example, a cycloalkylsubstituent may itself have a halide substituent at one or more of itsring carbons.

“Sulfanyl” refers to groups that include —S-(optionally substitutedalkyl), —S-(optionally substituted aryl), —S-(optionally substitutedheteroaryl) and —S-(optionally substituted heterocycloalkyl).

“Sulfinyl” refers to groups that include —S(O)—H, —S(O)-(optionallysubstituted alkyl), —S(O)-(optionally substituted amino),—S(O)-(optionally substituted aryl), —S(O)-(optionally substitutedheteroaryl) and —S(O)-(optionally substituted heterocycloalkyl).

“Sulfonyl” refers to groups that include —S(O₂)—H, —S(O₂)-(optionallysubstituted alkyl), —S(O₂)-(optionally substituted amino),—S(O₂)-(optionally substituted aryl), —S(O₂)-(optionally substitutedheteroaryl), and —S(O₂)-(optionally substituted heterocycloalkyl).

“Sulfonamidyl” or “sulfonamido” refers to a —S(═O)₂—NRR radical, whereeach R is selected independently from the group consisting of hydrogen,alkyl, cycloalkyl, aryl, heteroaryl (bonded through a ring carbon) andheteroalicyclic (bonded through a ring carbon). The R groups in —NRR ofthe —S(═O)₂—NRR radical may be taken together with the nitrogen to whichit is attached to form a 4-, 5-, 6- or 7-membered ring. A sulfonamidogroup is optionally substituted by one or more of the substituentsdescribed for alkyl, cycloalkyl, aryl, heteroaryl, respectively.

“Sulfoxyl” refers to a —S(═O)₂OH radical.

“Sulfonate” refers to a —S(═O)₂—OR radical, where R is selected from thegroup consisting of alkyl, cycloalkyl, aryl, heteroaryl (bonded througha ring carbon) and heteroalicyclic (bonded through a ring carbon). Asulfonate group is optionally substituted on R by one or more of thesubstituents described for alkyl, cycloalkyl, aryl, heteroaryl,respectively.

Compounds of the invention also include crystalline and amorphous formsof those compounds, including, for example, polymorphs,pseudopolymorphs, solvates, hydrates, unsolvated polymorphs (includinganhydrates), conformational polymorphs, and amorphous forms of thecompounds, as well as mixtures thereof. “Crystalline form” and“polymorph” are intended to include all crystalline and amorphous formsof the compound, including, for example, polymorphs, pseudopolymorphs,solvates, hydrates, unsolvated polymorphs (including anhydrates),conformational polymorphs, and amorphous forms, as well as mixturesthereof, unless a particular crystalline or amorphous form is referredto.

Compounds of the invention also include antibodies. The terms “antibody”and its plural form “antibodies” refer to whole immunoglobulins and anyantigen-binding fragment (“antigen-binding portion”) or single chainsthereof. An “antibody” further refers to a glycoprotein comprising atleast two heavy (H) chains and two light (L) chains inter-connected bydisulfide bonds, or an antigen-binding portion thereof. Each heavy chainis comprised of a heavy chain variable region (abbreviated herein asV_(H)) and a heavy chain constant region. The heavy chain constantregion is comprised of three domains, CH1, CH2 and CH3. Each light chainis comprised of a light chain variable region (abbreviated herein asV_(L)) and a light chain constant region. The light chain constantregion is comprised of one domain, C_(L). The V_(H) and V_(L) regions ofan antibody may be further subdivided into regions of hypervariability,which are referred to as complementarity determining regions (CDR) orhypervariable regions (HVR), and which can be interspersed with regionsthat are more conserved, termed framework regions (FR). Each V_(H) andV_(L) is composed of three CDRs and four FRs, arranged fromamino-terminus to carboxy-terminus in the following order: FR1, CDR1,FR2, CDR2, FR3, CDR3, FR4. The variable regions of the heavy and lightchains contain a binding domain that interacts with an antigen epitopeor epitopes. The constant regions of the antibodies may mediate thebinding of the immunoglobulin to host tissues or factors, includingvarious cells of the immune system (e.g., effector cells) and the firstcomponent (Clq) of the classical complement system.

The terms “monoclonal antibody,” “mAb,” “monoclonal antibodycomposition,” or their plural forms refer to a preparation of antibodymolecules of single molecular composition. A monoclonal antibodycomposition displays a single binding specificity and affinity for aparticular epitope. Monoclonal antibodies specific to CD20 can be madeusing knowledge and skill in the art of injecting test subjects withCD20 antigen and then isolating hybridomas expressing antibodies havingthe desired sequence or functional characteristics. DNA encoding themonoclonal antibodies is readily isolated and sequenced usingconventional procedures (e.g., by using oligonucleotide probes that arecapable of binding specifically to genes encoding the heavy and lightchains of the monoclonal antibodies). The hybridoma cells serve as apreferred source of such DNA. Once isolated, the DNA may be placed intoexpression vectors, which are then transfected into host cells such asE. coli cells, simian COS cells, Chinese hamster ovary (CHO) cells, ormyeloma cells that do not otherwise produce immunoglobulin protein, toobtain the synthesis of monoclonal antibodies in the recombinant hostcells. Recombinant production of antibodies will be described in moredetail below.

The terms “antigen-binding portion” or “antigen-binding fragment” of anantibody (or simply “antibody portion”), as used herein, refers to oneor more fragments of an antibody that retain the ability to specificallybind to an antigen such as CD20. It has been shown that theantigen-binding function of an antibody can be performed by fragments ofa full-length antibody. Examples of binding fragments encompassed withinthe term “antigen-binding portion” of an antibody include (i) a Fabfragment, a monovalent fragment consisting of the V_(L), V_(H), C_(L)and CH1 domains; (ii) a F(ab′)₂ fragment, a bivalent fragment comprisingtwo Fab fragments linked by a disulfide bridge at the hinge region;(iii) a Fd fragment consisting of the V_(H) and CH1 domains; (iv) a Fvfragment consisting of the V_(L) and V_(H) domains of a single arm of anantibody, (v) a domain antibody (dAb) fragment (Ward et al., Nature,1989, 341, 544-546), which may consist of a V_(H) or a V_(L) domain; and(vi) an isolated complementarity determining region (CDR). Furthermore,although the two domains of the Fv fragment, V_(L) and V_(H), are codedfor by separate genes, they can be joined, using recombinant methods, bya synthetic linker that enables them to be made as a single proteinchain in which the V_(L) and V_(H) regions pair to form monovalentmolecules known as single chain Fv (scFv); see, for example, Bird etal., Science 1988, 242, 423-426; and Huston et al., Proc. Natl. Acad.Sci. USA 1988, 85, 5879-5883). Such scFv chain antibodies are alsointended to be encompassed within the terms “antigen-binding portion” or“antigen-binding fragment” of an antibody. These antibody fragments areobtained using conventional techniques known to those with skill in theart, and the fragments are screened for utility in the same manner asare intact antibodies.

The term “human antibody,” as used herein, is intended to includeantibodies having variable regions in which both the framework and CDRregions are derived from human germline immunoglobulin sequences.Furthermore, if the antibody contains a constant region, the constantregion also is derived from human germline immunoglobulin sequences. Thehuman antibodies of the invention may include amino acid residues notencoded by human germline immunoglobulin sequences (e.g., mutationsintroduced by random or site-specific mutagenesis in vitro or by somaticmutation in vivo). The term “human antibody”, as used herein, is notintended to include antibodies in which CDR sequences derived from thegermline of another mammalian species, such as a mouse, have beengrafted onto human framework sequences.

The term “human monoclonal antibody” refers to antibodies displaying asingle binding specificity which have variable regions in which both theframework and CDR regions are derived from human germline immunoglobulinsequences. In one embodiment, the human monoclonal antibodies areproduced by a hybridoma which includes a B cell obtained from atransgenic nonhuman animal, e.g., a transgenic mouse, having a genomecomprising a human heavy chain transgene and a light chain transgenefused to an immortalized cell.

The term “recombinant human antibody”, as used herein, includes allhuman antibodies that are prepared, expressed, created or isolated byrecombinant means, such as (a) antibodies isolated from an animal (e.g.,a mouse) that is transgenic or transchromosomal for human immunoglobulingenes or a hybridoma prepared therefrom (described further below), (b)antibodies isolated from a host cell transformed to express the humanantibody, e.g., from a transfectoma, (c) antibodies isolated from arecombinant, combinatorial human antibody library, and (d) antibodiesprepared, expressed, created or isolated by any other means that involvesplicing of human immunoglobulin gene sequences to other DNA sequences.Such recombinant human antibodies have variable regions in which theframework and CDR regions are derived from human germline immunoglobulinsequences. In certain embodiments, however, such recombinant humanantibodies can be subjected to in vitro mutagenesis (or, when an animaltransgenic for human Ig sequences is used, in vivo somatic mutagenesis)and thus the amino acid sequences of the V_(H) and V_(L) regions of therecombinant antibodies are sequences that, while derived from andrelated to human germline V_(H) and V_(L) sequences, may not naturallyexist within the human antibody germline repertoire in vivo.

As used herein, “isotype” refers to the antibody class (e.g., IgM orIgG1) that is encoded by the heavy chain constant region genes.

The phrases “an antibody recognizing an antigen” and “an antibodyspecific for an antigen” are used interchangeably herein with the term“an antibody which binds specifically to an antigen.”

The term “human antibody derivatives” refers to any modified form of thehuman antibody, e.g., a conjugate of the antibody and another agent orantibody. The term “conjugate” or “immunoconjugate” refers to anantibody, or a fragment thereof, conjugated to a therapeutic moiety,such as a bacterial toxin, a cytotoxic drug or a radionuclide-containingtoxin. Toxic moieties can be conjugated to antibodies of the inventionusing methods available in the art.

The terms “humanized antibody,” “humanized antibodies,” and “humanized”are intended to refer to antibodies in which CDR sequences derived fromthe germline of another mammalian species, such as a mouse, have beengrafted onto human framework sequences. Additional framework regionmodifications may be made within the human framework sequences.Humanized forms of non-human (for example, murine) antibodies arechimeric antibodies that contain minimal sequence derived from non-humanimmunoglobulin. For the most part, humanized antibodies are humanimmunoglobulins (recipient antibody) in which residues from ahypervariable region of the recipient are replaced by residues from a 15hypervariable region of a non-human species (donor antibody) such asmouse, rat, rabbit or nonhuman primate having the desired specificity,affinity, and capacity. In some instances, Fv framework region (FR)residues of the human immunoglobulin are replaced by correspondingnon-human residues. Furthermore, humanized antibodies may compriseresidues that are not found in the recipient antibody or in the donorantibody. These modifications are made to further refine antibodyperformance. In general, the humanized antibody will comprisesubstantially all of at least one, and typically two, variable domains,in which all or substantially all of the hypervariable loops correspondto those of a non-human immunoglobulin and all or substantially all ofthe FR regions are those of a human immunoglobulin sequence. Thehumanized antibody optionally also will comprise at least a portion ofan immunoglobulin constant region (Fc), typically that of a humanimmunoglobulin. For further details, see Jones et al., Nature 1986, 321,522-525; Riechmann et al., Nature 1988, 332, 323-329; and Presta, Curr.Op. Struct. Biol. 1992, 2, 593-596.

The term “chimeric antibody” is intended to refer to antibodies in whichthe variable region sequences are derived from one species and theconstant region sequences are derived from another species, such as anantibody in which the variable region sequences are derived from a mouseantibody and the constant region sequences are derived from a humanantibody.

A “diabody” is a small antibody fragment with two antigen-binding sites.The fragment comprises a heavy chain variable domain (V_(H)) connectedto a light chain variable domain (V_(L)) in the same polypeptide chain(V_(H)-V_(L) or V_(L)-V_(H)). By using a linker that is too short toallow pairing between the two domains on the same chain, the domains areforced to pair with the complementary domains of another chain andcreate two antigen-binding sites. Diabodies are described more fully in,e.g., European Patent No. EP 404,097, International Patent PublicationNo. WO 93/11161; and Bolliger et al., Proc. Natl. Acad. Sci. USA 1993,90, 6444-6448.

The term “glycosylation” refers to a modified derivative of an antibody.An aglycoslated antibody lacks glycosylation. Glycosylation can bealtered to, for example, increase the affinity of the antibody forantigen. Such carbohydrate modifications can be accomplished by, forexample, altering one or more sites of glycosylation within the antibodysequence. For example, one or more amino acid substitutions can be madethat result in elimination of one or more variable region frameworkglycosylation sites to thereby eliminate glycosylation at that site.Aglycosylation may increase the affinity of the antibody for antigen, asdescribed in U.S. Pat. Nos. 5,714,350 and 6,350,861. Additionally oralternatively, an antibody can be made that has an altered type ofglycosylation, such as a hypofucosylated antibody having reduced amountsof fucosyl residues or an antibody having increased bisecting GlcNacstructures. Such altered glycosylation patterns have been demonstratedto increase the ability of antibodies. Such carbohydrate modificationscan be accomplished by, for example, expressing the antibody in a hostcell with altered glycosylation machinery. Cells with alteredglycosylation machinery have been described in the art and can be usedas host cells in which to express recombinant antibodies of theinvention to thereby produce an antibody with altered glycosylation. Forexample, the cell lines Ms704, Ms705, and Ms709 lack thefucosyltransferase gene, FUT8 (alpha (1,6) fucosyltransferase), suchthat antibodies expressed in the Ms704, Ms705, and Ms709 cell lines lackfucose on their carbohydrates. The Ms704, Ms705, and Ms709 FUT8−/− celllines were created by the targeted disruption of the FUT8 gene inCHO/DG44 cells using two replacement vectors (see e.g. U.S. PatentPublication No. 2004/0110704 or Yamane-Ohnuki, et al., Biotechnol.Bioeng., 2004, 87, 614-622). As another example, European Patent No. EP1,176,195 describes a cell line with a functionally disrupted FUT8 gene,which encodes a fucosyl transferase, such that antibodies expressed insuch a cell line exhibit hypofucosylation by reducing or eliminating thealpha 1,6 bond-related enzyme, and also describes cell lines which havea low enzyme activity for adding fucose to the N-acetylglucosamine thatbinds to the Fc region of the antibody or does not have the enzymeactivity, for example the rat myeloma cell line YB2/0 (ATCC CRL 1662).International Patent Publication WO 03/035835 describes a variant CHOcell line, Lec 13 cells, with reduced ability to attach fucose toAsn(297)-linked carbohydrates, also resulting in hypofucosylation ofantibodies expressed in that host cell (see also Shields, et al., J.Biol. Chem. 2002, 277, 26733-26740. International Patent Publication WO99/54342 describes cell lines engineered to expressglycoprotein-modifying glycosyl transferases (e.g.,beta(1,4)-N-acetylglucosaminyltransferase III (GnTIII)) such thatantibodies expressed in the engineered cell lines exhibit increasedbisecting GlcNac structures which results in increased ADCC activity ofthe antibodies (see also Umana, et al., Nat. Biotech. 1999, 17,176-180). Alternatively, the fucose residues of the antibody may becleaved off using a fucosidase enzyme. For example, the fucosidasealpha-L-fucosidase removes fucosyl residues from antibodies as describedin Tarentino, et al., Biochem. 1975, 14, 5516-5523.

“Pegylation” refers to a modified antibody, or a fragment thereof, thattypically is reacted with polyethylene glycol (PEG), such as a reactiveester or aldehyde derivative of PEG, under conditions in which one ormore PEG groups become attached to the antibody or antibody fragment.Pegylation may, for example, increase the biological (e.g., serum) halflife of the antibody. Preferably, the pegylation is carried out via anacylation reaction or an alkylation reaction with a reactive PEGmolecule (or an analogous reactive water-soluble polymer). As usedherein, the term “polyethylene glycol” is intended to encompass any ofthe forms of PEG that have been used to derivatize other proteins, suchas mono (C₁-C₁₀) alkoxy- or aryloxy-polyethylene glycol or polyethyleneglycol-maleimide. The antibody to be pegylated may be an aglycosylatedantibody. Methods for pegylation are known in the art and can be appliedto the antibodies of the invention. See, for example, European PatentNos. EP 0154316 and EP 0401384.

As used herein, an antibody that “specifically binds to human CD20” isintended to refer to an antibody that binds to human CD20 with a K_(D)of 1×10⁻⁷ M or less, more preferably 5×10⁻⁸ M or less, more preferably1×10⁻⁸ M or less, more preferably 5×10⁻⁹ M or less.

The term “radioisotope-labeled complex” refers to both non-covalent andcovalent attachment of a radioactive isotope, such as ⁹⁰Y, ¹¹¹In, or¹³¹I, to an antibody.

The term “biosimilar” means a biological product that is highly similarto a U.S. licensed reference biological product notwithstanding minordifferences in clinically inactive components, and for which there areno clinically meaningful differences between the biological product andthe reference product in terms of the safety, purity, and potency of theproduct. Furthermore, a similar biological or “biosimilar” medicine is abiological medicine that is similar to another biological medicine thathas already been authorized for use by the European Medicines Agency.The term “biosimilar” is also used synonymously by other national andregional regulatory agencies. Biological products or biologicalmedicines are medicines that are made by or derived from a biologicalsource, such as a bacterium or yeast. They can consist of relativelysmall molecules such as human insulin or erythropoietin, or complexmolecules such as monoclonal antibodies. For example, if the referenceanti-CD20 monoclonal antibody is rituximab, an anti-CD20 biosimilarmonoclonal antibody approved by drug regulatory authorities withreference to rituximab is a “biosimilar to” rituximab or is a“biosimilar thereof” rituximab.

Described below are non-limiting exemplary pharmaceutical compositionsand methods for preparing the same.

Pharmaceutical Compositions for Oral Administration

In selected embodiments, the invention provides a pharmaceuticalcomposition for oral administration containing a BTK inhibitor ofFormula (I) or Formula (II), and a pharmaceutical excipient suitable fororal administration.

In selected embodiments, the invention provides a solid pharmaceuticalcomposition for oral administration containing: (i) an effective amountof a BTK inhibitor of Formula (I) or Formula (II), in combination and(ii) a pharmaceutical excipient suitable for oral administration. Inselected embodiments, the composition further contains (iii) aneffective amount of at least one additional active ingredient.

In selected embodiments, the pharmaceutical composition may be a liquidpharmaceutical composition suitable for oral consumption. Pharmaceuticalcompositions of the invention suitable for oral administration can bepresented as discrete dosage forms, such as capsules, cachets, ortablets, or liquids or aerosol sprays each containing a predeterminedamount of an active ingredient as a powder or in granules, a solution,or a suspension in an aqueous or non-aqueous liquid, an oil-in-wateremulsion, or a water-in-oil liquid emulsion. Such dosage forms can beprepared by any of the methods of pharmacy, but all methods include thestep of bringing the active ingredient(s) into association with thecarrier, which constitutes one or more necessary ingredients. Ingeneral, the compositions are prepared by uniformly and intimatelyadmixing the active ingredient(s) with liquid carriers or finely dividedsolid carriers or both, and then, if necessary, shaping the product intothe desired presentation. For example, a tablet can be prepared bycompression or molding, optionally with one or more accessoryingredients. Compressed tablets can be prepared by compressing in asuitable machine the active ingredient in a free-flowing form such aspowder or granules, optionally mixed with an excipient such as, but notlimited to, a binder, a lubricant, an inert diluent, and/or a surfaceactive or dispersing agent. Molded tablets can be made by molding in asuitable machine a mixture of the powdered compound moistened with aninert liquid diluent.

The invention further encompasses anhydrous pharmaceutical compositionsand dosage forms since water can facilitate the degradation of somecompounds. For example, water may be added (e.g., 5%) in thepharmaceutical arts as a means of simulating long-term storage in orderto determine characteristics such as shelf-life or the stability offormulations over time. Anhydrous pharmaceutical compositions and dosageforms of the invention can be prepared using anhydrous or low moisturecontaining ingredients and low moisture or low humidity conditions.Pharmaceutical compositions and dosage forms of the invention whichcontain lactose can be made anhydrous if substantial contact withmoisture and/or humidity during manufacturing, packaging, and/or storageis expected. An anhydrous pharmaceutical composition may be prepared andstored such that its anhydrous nature is maintained. Accordingly,anhydrous compositions may be packaged using materials known to preventexposure to water such that they can be included in suitable formularykits. Examples of suitable packaging include, but are not limited to,hermetically sealed foils, plastic or the like, unit dose containers,blister packs, and strip packs.

The BTK inhibitors of Formula (I) or Formula (II) can be combined in anintimate admixture with a pharmaceutical carrier according toconventional pharmaceutical compounding techniques. The carrier can takea wide variety of forms depending on the form of preparation desired foradministration. In preparing the compositions for an oral dosage form,any of the usual pharmaceutical media can be employed as carriers, suchas, for example, water, glycols, oils, alcohols, flavoring agents,preservatives, coloring agents, and the like in the case of oral liquidpreparations (such as suspensions, solutions, and elixirs) or aerosols;or carriers such as starches, sugars, micro-crystalline cellulose,diluents, granulating agents, lubricants, binders, and disintegratingagents can be used in the case of oral solid preparations, in someembodiments without employing the use of lactose. For example, suitablecarriers include powders, capsules, and tablets, with the solid oralpreparations. If desired, tablets can be coated by standard aqueous ornonaqueous techniques.

Binders suitable for use in pharmaceutical compositions and dosage formsinclude, but are not limited to, corn starch, potato starch, or otherstarches, gelatin, natural and synthetic gums such as acacia, sodiumalginate, alginic acid, other alginates, powdered tragacanth, guar gum,cellulose and its derivatives (e.g., ethyl cellulose, cellulose acetate,carboxymethyl cellulose calcium, sodium carboxymethyl cellulose),polyvinyl pyrrolidone, methyl cellulose, pre-gelatinized starch,hydroxypropyl methyl cellulose, microcrystalline cellulose, and mixturesthereof.

Examples of suitable fillers for use in the pharmaceutical compositionsand dosage forms disclosed herein include, but are not limited to, talc,calcium carbonate (e.g., granules or powder), microcrystallinecellulose, powdered cellulose, dextrates, kaolin, mannitol, silicicacid, sorbitol, starch, pre-gelatinized starch, and mixtures thereof.

Disintegrants may be used in the compositions of the invention toprovide tablets that disintegrate when exposed to an aqueousenvironment. Too much of a disintegrant may produce tablets whichdisintegrate in the bottle. Too little may be insufficient fordisintegration to occur, thus altering the rate and extent of release ofthe active ingredients from the dosage form. Thus, a sufficient amountof disintegrant that is neither too little nor too much to detrimentallyalter the release of the active ingredient(s) may be used to form thedosage forms of the compounds disclosed herein. The amount ofdisintegrant used may vary based upon the type of formulation and modeof administration, and may be readily discernible to those of ordinaryskill in the art. About 0.5 to about 15 weight percent of disintegrant,or about 1 to about 5 weight percent of disintegrant, may be used in thepharmaceutical composition. Disintegrants that can be used to formpharmaceutical compositions and dosage forms of the invention include,but are not limited to, agar-agar, alginic acid, calcium carbonate,microcrystalline cellulose, croscarmellose sodium, crospovidone,polacrilin potassium, sodium starch glycolate, potato or tapioca starch,other starches, pre-gelatinized starch, other starches, clays, otheralgins, other celluloses, gums or mixtures thereof.

Lubricants which can be used to form pharmaceutical compositions anddosage forms of the invention include, but are not limited to, calciumstearate, magnesium stearate, mineral oil, light mineral oil, glycerin,sorbitol, mannitol, polyethylene glycol, other glycols, stearic acid,sodium lauryl sulfate, talc, hydrogenated vegetable oil (e.g., peanutoil, cottonseed oil, sunflower oil, sesame oil, olive oil, corn oil, andsoybean oil), zinc stearate, ethyl oleate, ethylaureate, agar, ormixtures thereof. Additional lubricants include, for example, a syloidsilica gel, a coagulated aerosol of synthetic silica, or mixturesthereof. A lubricant can optionally be added, in an amount of less thanabout 1 weight percent of the pharmaceutical composition.

When aqueous suspensions and/or elixirs are desired for oraladministration, the essential active ingredient therein may be combinedwith various sweetening or flavoring agents, coloring matter or dyesand, if so desired, emulsifying and/or suspending agents, together withsuch diluents as water, ethanol, propylene glycol, glycerin and variouscombinations thereof.

The tablets can be uncoated or coated by known techniques to delaydisintegration and absorption in the gastrointestinal tract and therebyprovide a sustained action over a longer period. For example, a timedelay material such as glyceryl monostearate or glyceryl distearate canbe employed. Formulations for oral use can also be presented as hardgelatin capsules wherein the active ingredient is mixed with an inertsolid diluent, for example, calcium carbonate, calcium phosphate orkaolin, or as soft gelatin capsules wherein the active ingredient ismixed with water or an oil medium, for example, peanut oil, liquidparaffin or olive oil.

Surfactants which can be used to form pharmaceutical compositions anddosage forms of the invention include, but are not limited to,hydrophilic surfactants, lipophilic surfactants, and mixtures thereof.That is, a mixture of hydrophilic surfactants may be employed, a mixtureof lipophilic surfactants may be employed, or a mixture of at least onehydrophilic surfactant and at least one lipophilic surfactant may beemployed.

A suitable hydrophilic surfactant may generally have an HLB value of atleast 10, while suitable lipophilic surfactants may generally have anHLB value of or less than about 10. An empirical parameter used tocharacterize the relative hydrophilicity and hydrophobicity of non-ionicamphiphilic compounds is the hydrophilic-lipophilic balance (“HLB”value). Surfactants with lower HLB values are more lipophilic orhydrophobic, and have greater solubility in oils, while surfactants withhigher HLB values are more hydrophilic, and have greater solubility inaqueous solutions. Hydrophilic surfactants are generally considered tobe those compounds having an HLB value greater than about 10, as well asanionic, cationic, or zwitterionic compounds for which the HLB scale isnot generally applicable. Similarly, lipophilic (i.e., hydrophobic)surfactants are compounds having an HLB value equal to or less thanabout 10. However, HLB value of a surfactant is merely a rough guidegenerally used to enable formulation of industrial, pharmaceutical andcosmetic emulsions.

EXAMPLES

The embodiments encompassed herein are now described with reference tothe following examples. These examples are provided for the purpose ofillustration only and the disclosure encompassed herein should in no waybe construed as being limited to these examples, but rather should beconstrued to encompass any and all variations which become evident as aresult of the teachings provided herein.

Example 1—Preclinical Study of a Second Generation BTK Inhibitor for Usein CLL/SLL

The BTK inhibitor ibrutinib((1-[(3R)-3-[4-amino-3-(4-phenoxyphenyl)-1H-pyrazolo[3,4-d]pyrimidin-1-yl]piperidin-1-yl]prop-2-en-1-one)is a first-generation BTK inhibitor. In clinical testing as amonotherapy in subjects with hematologic malignancies, ibrutinib wasgenerally well tolerated at dose levels through 840 mg (the highest dosetested). R. H. Advani, et al., J. Clin. Oncol. 2013, 31, 88-94; J. C.Byrd, et al., N. Engl. J. Med. 2013, 369, 32-42; M. L. Wang, et al., N.Engl. J. Med. 2013, 369, 507-16. No maximum tolerated dose (MTD) wasapparent within the tested dose range. Furthermore, subjects typicallyfound the drug tolerable over periods extending to >2 years. No subjecthad tumor lysis syndrome. No overt pattern of myelosuppression wasassociated with ibrutinib treatment. No drug-related reductions incirculating CD4⁺ T cells or serum immunoglobulins were noted. Adverseevents with an apparent relationship to study drug included diarrhea andrash.

In subjects with heavily pretreated non-Hodgkin lymphoma (NHL),ibrutinib showed substantial antitumor activity, inducing durableregressions of lymphadenopathy and splenomegaly in most subjects.Improvements in disease-associated anemia and thrombocytopenia wereobserved. The pattern of changes in subjects with CLL was notable.Single-agent ibrutinib caused rapid and substantial reductions in lymphnode size concomitant with a redistribution of malignant sites into theperipheral blood. An asymptomatic absolute lymphocyte count (ALC)increase was observed that was maximal during the first few months oftreatment and generally decreased thereafter but could be persistent insome subjects or could be seen repeatedly in subjects who hadinterruption and resumption of drug therapy.

Collectively, these data with ibrutinib support the potential benefitsof selective BTK inhibition in the treatment of subjects with relapsedlymphoid cancers. However, while highly potent in inhibiting BTK,ibrutinib has also shown in vitro activity against other kinases with acysteine in the same position as Cys481 in BTK to which the drugcovalently binds. For example, ibrutinib inhibits epidermal growthfactor receptor (EGFR), which may be the cause of ibrutinib-relateddiarrhea and rash. In addition, it is a substrate for both cytochromeP450 (CYP) enzymes 3A4/5 and 2D6, which increases the possibility ofdrug-drug interactions. These liabilities support the development ofalternative BTK inhibitors for use in the therapy of lymphoid cancer.

The preclinical selectivity and potency characteristics of thesecond-generation BTK inhibitor of Formula (II) were compared to thefirst-generation BTK inhibitor ibrutinib. In Table 1, a kinome screen(performed Life Technologies or based on literature data) is shown thatcompares these compounds.

The results shown in Table 1 are obtained from a 10 point biochemicalassay generated from 10 point concentration curves. The BTK inhibitor ofFormula (II) shows much greater selectivity for BTK compared to otherkinases than ibrutinib.

A comparison of the in vivo potency results for the BTK inhibitors ofFormula (II) and ibrutinib is shown in FIG. 1. CD86 and CD69 are cellsurface proteins that are BCR activation markers. To obtain the in vivopotency results, mice were gavaged at increasing drug concentration andsacrificed at one time point (3 h post-dose). BCR was stimulated withIgM and the expression of activation marker CD69 and CD86 are monitoredby flow cytometry and to determine EC₅₀ values.

Formula (II) is currently being evaluated in an ongoing study of caninespontaneous B-cell lymphoma. Six dogs have been treated with Formula(II) using 2.5 mg/kg once daily oral administration for an average of 22days (range 14 to 42 days). To date, partial remission (PR), perVeterinary Cooperative Oncology Group criteria for assessment ofresponse in peripheral nodal lymphoma, has been observed in 2 of 6 dogs.D. M. Vali, et al., Vet. Comp. Oncol. 8, 28-37 (2010). No drug-relatedadverse events have been reported to date in this study. These findingsare preliminary and similar to the clinical responses (i.e., 3 dogs withPR out of 8 dogs treated) observed with ibrutinib in dogs withspontaneous B-cell lymphoma. L. A. Honigberg, et al., Proc. Nat. Acad.Sci. USA, 107, 13075-13080 (2010).

In vitro and in vivo safety pharmacology studies with Formula (II) havedemonstrated a favorable nonclinical safety profile. When screened at 10μM in binding assays evaluating interactions with 80 known pharmacologictargets such as G-protein-coupled receptors, nuclear receptors,proteases, and ion channels, Formula (II) shows significant activityonly against the A3 adenosine receptor; follow-up dose-responseexperiments indicated a IC₅₀ of 2.7 μM, suggesting a low clinical riskof off-target effects. Formula (II) at 10 μM showed no inhibition of invitro EGFR phosphorylation in an A431 human epidermoid cancer cell linewhereas ibrutinib had an IC₅₀ of 66 nM. The in vitro effect of Formula(II) on human ether-a-go-go-related gene (hERG) channel activity wasinvestigated in vitro in human embryonic kidney cells stably transfectedwith hERG. Formula (II) inhibited hERG channel activity by 25% at 10 μM,suggesting a low clinical risk that Formula (II) would induce clinicalQT prolongation as predicted by this assay. Formula (II) was welltolerated in standard in vivo Good Laboratory Practices (GLP) studies ofpharmacologic safety. A functional observation battery in rats at dosesof through 300 mg/kg (the highest dose level) revealed no adverseeffects on neurobehavioral effects or body temperature at any doselevel. A study of respiratory function in rats also indicated notreatment-related adverse effects at doses through 300 mg/kg (thehighest dose level). In a cardiovascular function study in awaketelemeterized male beagle dogs, single doses of Formula (II) at doselevels through 30 mg/kg (the highest dose level) induced no meaningfulchanges in body temperature, cardiovascular, or electrocardiographic(ECG) (including QT interval) parameters. The results suggest thatFormula (II) is unlikely to cause serious off-target effects or adverseeffects on critical organ systems.

The drug-drug interaction potential of Formula (II) was also evaluated.In vitro experiments evaluating loss of parent drug as catalyzed by CYPsindicated that Formula (II) is metabolized by CYP3A4. In vitrometabolism studies using mouse, rat, dog, rabbit, monkey, and humanhepatocytes incubated with ¹⁴C-labeled Formula (II) indicated twomono-oxidized metabolites and a glutathione conjugate. No unique humanmetabolite was identified. Preliminary evaluations of metabolism in theplasma, bile, and urine of rats, dogs, and monkeys indicated metabolicprocesses of oxidation, glutathione binding, and hydrolysis. It wasshown that Formula (II) binds to glutathione but does not depleteglutathione in vitro. Nonclinical CYP interaction studies data indicatethat Formula (II) is very unlikely to cause clinical drug-druginteractions through alteration of the metabolism of drugs that aresubstrates for CYP enzymes.

Example 2—Clinical Study of a Second Generation BTK Inhibitor for Use inCLL/SLL

Clinical studies have shown that targeting the BCR signaling pathway byinhibiting BTK produces significant clinical benefit in patients withnon-Hodgkin's lymphoma (NHL). The second generation BTK inhibitor,Formula (II), achieves significant oral bioavailability and potency, andhas favorable preclinical characteristics, as described above. Thepurpose of this study is to evaluate the safety and efficacy of thesecond generation BTK inhibitor of Formula (II) in treating subjectswith chronic lymphocytic leukemia (CLL) and small lymphocytic lymphoma(SLL).

The design and conduct of this study is supported by an understanding ofthe history and current therapies for subjects with lymphoid cancers;knowledge of the activity and safety of a first-generation BTKinhibitor, ibrutinib, in subjects with hematologic cancers; and theavailable nonclinical information regarding Formula (II). The collectivedata support the following conclusions. BTK expression plays animportant role in the biology of lymphoid neoplasms, which representserious and life-threatening disorders with continuing unmet medicalneed. Clinical evaluation of Formula (II) as a potential treatment forthese disorders has sound scientific rationale based on observationsthat the compound selectively abrogates BTK activity and shows activityin nonclinical models of lymphoid cancers. These data are supported byclinical documentation that ibrutinib, a first-generation BTK inhibitor,is clinically active in these diseases. Ibrutinib clinical data andFormula (II) nonclinical safety pharmacology and toxicology studiessupport the safety of testing Formula (II) in subjects with B cellmalignancies.

The primary objectives of the clinical study are as follows: (1)establish the safety and the MTD of orally administered Formula (II) insubjects with CLL/SLL; (2) determine pharmacokinetics (PK) of orallyadministered Formula (II) and identification of its major metabolite(s);and (3) measure pharmacodynamic (PD) parameters including drug occupancyof BTK, the target enzyme, and effect on biologic markers of B cellfunction.

The secondary objective of the clinical study is to evaluate tumorresponses in patients treated with Formula (II).

This study is a multicenter, open-label, nonrandomized, sequentialgroup, dose escalation study. The following dose cohorts will beevaluated:

-   -   Cohort 1: 100 mg/day for 28 days (=1 cycle)    -   Cohort 2: 175 mg/day for 28 days (=1 cycle)    -   Cohort 3: 250 mg/day for 28 days (=1 cycle)    -   Cohort 4: 350 mg/day for 28 days (=1 cycle)    -   Cohort 5: 450 mg/day for 28 days (=1 cycle)    -   Cohort 6: To be determined amount in mg/day for 28 days (=1        cycle)

Each cohort will be enrolled sequentially with 6 subjects per cohort. If1 dose-limiting toxicity (DLT) is observed in the cohort during Cycle 1,escalation to the next cohort will proceed. Subjects may be enrolled inthe next cohort if 4 of the 6 subjects enrolled in the cohort completedCycle 1 without experiencing a DLT, while the remaining 2 subjects arecompleting evaluation. If ≥2 DLTs are observed during Cycle 1, dosing atthat dose and higher will be suspended and the MTD will be establishedas the previous cohort. The MTD is defined as the largest daily dose forwhich fewer than 33% of the subjects experience a DLT during Cycle 1.Dose escalation will end when either the MTD is achieved or at 3 doselevels above full BTK occupancy, whichever occurs first. Full BTKoccupancy is defined as Formula (II) active-site occupancy of >80%(average of all subjects in cohort) at 24 hours postdose. Shouldescalation to Cohort 6 be necessary, the dose will be determined basedon the aggregate data from Cohorts 1 to 5, which includes safety,efficacy, and PK/PD results. The dose for Cohort 6 will not exceed 900mg/day.

Treatment with Formula (II) may be continued for >28 days until diseaseprogression or an unacceptable drug-related toxicity occurs. Subjectswith disease progression will be removed from the study. All subjectswho discontinue study drug will have a safety follow-up visit 30 (+7)days after the last dose of study drug unless they have started anothercancer therapy within that timeframe. Radiologic tumor assessment willbe done at screening and at the end of Cycle 2, Cycle 4, and Cycle 12and at investigator discretion. Confirmation of complete response (CR)will require bone marrow analysis and radiologic tumor assessment. Forsubjects who remain on study for >11 months, a mandatory bone marrowaspirate and biopsy is required in Cycle 12 concurrent with theradiologic tumor assessment.

All subjects will have standard hematology, chemistry, and urinalysissafety panels done at screening. This study also includes pancreaticfunction assessment (serum amylase and serum lipase) due to thepancreatic findings in the 28-day GLP rat toxicity study. Once dosingcommences, all subjects will be evaluated for safety once weekly for thefirst 4 weeks, every other week for Cycle 2, and monthly thereafter.Blood samples will be collected during the first week of treatment forPK/PD assessments. ECGs will be done at screening, and on Day 1-2, 8,15, 22, 28 of Cycle 1, Day 15 and 28 of Cycle 2, and monthly thereafterthrough Cycle 6. ECGs are done in triplicate for screening only.Thereafter, single ECG tests are done unless a repeat ECG testing isrequired.

Dose-limiting toxicity is defined as any of the following events (if notrelated to disease progression): (1) any Grade≥3 non-hematologictoxicity (except alopecia) persisting despite receipt of a single courseof standard outpatient symptomatic therapy (e.g., Grade 3 diarrhea thatresponds to a single, therapeutic dose of Imodium® would not beconsidered a DLT); (2) grade≥3 prolongation of the corrected QT interval(QTc), as determined by a central ECG laboratory overread; (3) grade 4neutropenia (absolute neutrophil count [ANC]<500/μL) lasting >7 daysafter discontinuation of therapy without growth factors or lasting >5days after discontinuation of therapy while on growth factors (i.e.,Grade 4 neutropenia not lasting as long as specified will not beconsidered a DLT), (4) grade 4 thrombocytopenia (platelet count<20,000/μL) lasting >7 days after discontinuation of therapy orrequiring transfusion (i.e., Grade 4 thrombocytopenia not lasting aslong as specified will not be considered a DLT), and (5) dosing delaydue to toxicity for >7 consecutive days.

The efficacy parameters for the study include overall response rate,duration of response, and progression-free survival (PFS). The safetyparameters for the study include DLTs and MTD, frequency, severity, andattribution of adverse events (AEs) based on the Common TerminologyCriteria for Adverse Events (CTCAE v4.03) for non-hematologic AEs. M.Hallek, et al., Blood 2008, 111, 5446-5456.

The schedule of assessments is as follows, with all days stated in thefollowing meaning the given day or +/−2 days from the given day. Aphysical examination, including vital signs and weight, are performed atscreening, during cycle 1 at 1, 8, 15, 22, and 28 days, during cycle 2at 15 and 28 days, during cycles 3 to 24 at 28 days, and at follow up(after the last dose). The screening physical examination includes, at aminimum, the general appearance of the subject, height (screening only)and weight, and examination of the skin, eyes, ears, nose, throat,lungs, heart, abdomen, extremities, musculoskeletal system, lymphaticsystem, and nervous system. Symptom-directed physical exams are donethereafter. Vital signs (blood pressure, pulse, respiratory rate, andtemperature) are assessed after the subject has rested in the sittingposition. Eastern Cooperative Oncology Group (ECOG) status is assessedat screening, during cycle 1 at 1, 8, 15, 22, and 28 days, during cycle2 at 15 and 28 days, during cycles 3 to 24 at 28 days, and at follow up,using the published ECOG performance status indications described in M.M. Oken, et al., Am. J. Clin. Oncol. 1982, 5, 649-655. ECG testing isperformed at screening, during cycle 1 at 1, 2, 8, 15, 22, and 28 days,during cycle 2 at 15 and 28 days, during cycles 3 to 24 at 28 days, andat follow up. The 12-lead ECG test will be done in triplicate (≥1 minuteapart) at screening. The calculated QTc average of the 3 ECGs must be<480 ms for eligibility. On cycle 1, day 1 and cycle 1, day 8, singleECGs are done predose and at 1, 2, 4, and 6 h postdose. The single ECGon Cycle 1 Day 2 is done predose. On cycle 1, day 15, day 22, and day28, a single ECG is done 2 hours post-dose. Starting with cycle 2, asingle ECG is done per visit. Subjects should be in supine position andresting for at least 10 minutes before study-related ECGs. Twoconsecutive machine-read QTc >500 ms or >60 ms above baseline requirecentral ECG review. Hematology, including complete blood count withdifferential and platelet and reticulocyte counts, is assesed atscreening, during cycle 1 at 1, 8, 15, 22, and 28 days, during cycle 2at 15 and 28 days, during cycles 3 to 24 at 28 days, and at follow up.Serum chemistry is assesed at screening, during cycle 1 at 1, 8, 15, 22,and 28 days, during cycle 2 at 15 and 28 days, during cycles 3 to 24 at28 days, and at follow up. Serum chemistry includes albumin, alkalinephosphatase, ALT, AST, bicarbonate, blood urea nitrogen (BUN), calcium,chloride, creatinine, glucose, lactate dehydrogenase (LDH), magnesium,phosphate, potassium, sodium, total bilirubin, total protein, and uricacid. Cell counts and serum immunoglobulin are performed at screening,at cycle 2, day 28, and at every 6 months thereafter until last dose andinclude T/B/NK/monocyte cell counts (CD3, CD4, CD8, CD14, CD19, CD19,CD16/56, and others as needed) and serum immunoglobulin (IgG, IgM, IgA,and total immunoglobulin). Bone marrow aspirates are performed at cycle12. Pharmacodynamics samples are drawn during cycle 1 at 1, 2, and 8days, and at follow up. On days 1 and 8, pharmacodynamic samples aredrawn pre-dose and 4 hours (+10 minutes) post-dose, and on day 2,pharmacodynamic samples are drawn pre-dose. Pharmacokinetics samples aredrawn during cycle 1 at 1, 2, 8, 15, 22, and 28 days. Pharmacokineticsamples for Cycle 1 Day 1 are drawn pre-dose and at 0.5, 1, 2, 4, 6 and24 hours (before dose on Day 2) post-dose. Samples for Cycle 1 Day 8 aredrawn pre-dose and at 0.5, 1, 2, 4, and 6 hours post-dose. On Cycle 1Day 15, 22, and 28, a PK sample is drawn pre-dose and the second PKsample must be drawn before (up to 10 minutes before) the ECGacquisition, which is 2 hours postdose. Pretreatment radiologic tumorassessments are performed within 30 days before the first dose. Acomputed tomography (CT) scan (with contrast unless contraindicated) isrequired of the chest, abdomen, and pelvis. In addition, a positronemission tomography (PET) or PET/CT must done for subjects with SLL.Radiologic tumor assessments are mandatory at the end of Cycle 2 (−7days), Cycle 4 (−7 days), and Cycle 12 (−7 days). Otherwise, radiologictumor assessments are done at investigator discretion. A CT (withcontrast unless contraindicated) scan of the chest, abdomen, and pelvisis required for subjects with CLL. In addition, a PET/CT is required insubjects with SLL. Bone marrow and radiologic assessments are bothrequired for confirmation of a complete response (CR). Clinicalassessments of tumor response should be done at the end of Cycle 6 andevery 3 months thereafter. Molecular markers are measured at screening,and include interphase cytogenetics, stimulated karyotype, IgHVmutational status, Zap-70 methylation, and beta-2 microglobulin levels.Urinalysis is performed at screening, and includes pH, ketones, specificgravity, bilirubin, protein, blood, and glucose. Other assessments,including informed consent, eligibility, medical history, and pregnancytest are done at the time of screening.

The investigator rates the subject's response to treatment based onrecent guidelines for CLL, as given in M. Hallek, et al., Blood 2008,111, 5446-56, and for SLL, as given in B. D. Cheson, et al., J. Clin.Oncol. 2007, 25, 579-586. The response assessment criteria for CLL aresummarized in Table 2.

The PK parameters of the study are as follows. The plasma PK of Formula(II) and a metabolite is characterized using noncompartmental analysis.The following PK parameters are calculated, whenever possible, fromplasma concentrations of Formula (II):

-   -   AUC_((0-t)): Area under the plasma concentration-time curve        calculated using linear trapezoidal summation from time 0 to        time t, where t is the time of the last measurable concentration        (Ct),    -   AUC₍₀₋₂₄₎: Area under the plasma concentration-time curve from 0        to 24 hours, calculated using linear trapezoidal summation,    -   AUC_((0-∞)): Area under the plasma concentration-time curve from        0 to infinity, calculated using the formula:        AUC_((0-∞))=AUC_((0-t))+Ct/λz, where λz is the apparent terminal        elimination rate constant,    -   C_(max): Maximum observed plasma concentration,    -   T_(max): Time of the maximum plasma concentration (obtained        without interpolation),    -   t_(1/2): Terminal elimination half-life (whenever possible),    -   λ_(z): Terminal elimination rate constant (whenever possible),    -   Cl/F: Oral clearance.

The PD parameters of the study are as follows. The occupancy of BTK byFormula (II) are measured in peripheral blood mononuclear cells (PBMCs)with the aid of a biotin-tagged Formula (II) analogue probe. The effectof Formula (II) on biologic markers of B cell function will also beevaluated.

The statistical analysis used in the study is as follows. No formalstatistical tests of hypotheses are performed. Descriptive statistics(including means, standard deviations, and medians for continuousvariables and proportions for discrete variables) are used to summarizedata as appropriate.

The following definitions are used for the safety and efficacy analysissets: Safety analysis set: All enrolled subjects who receive ≥1 dose ofstudy drug; Per-protocol (PP) analysis set: All enrolled subjects whoreceive ≥1 dose of study drug and with ≥1 tumor response assessmentafter treatment. The safety analysis set will be used for evaluating thesafety parameters in this study. The PP analysis sets will be analyzedfor efficacy parameters in this study.

No imputation of values for missing data is performed except for missingor partial start and end dates for adverse events and concomitantmedication will be imputed according to prespecified, conservativeimputation rules. Subjects lost to follow-up (or drop out) will beincluded in statistical analyses to the point of their last evaluation.

The safety endpoint analysis was performed as follows. Safety summarieswill include summaries in the form of tables and listings. The frequency(number and percentage) of treatment emergent adverse events will bereported in each treatment group by Medical Dictionary for RegulatoryActivities (MedDRA) System Organ Class and Preferred Term. Summarieswill also be presented by the severity of the adverse event and byrelationship to study drug. Laboratory shift tables containing countsand percentages will be prepared by treatment assignment, laboratoryparameter, and time. Summary tables will be prepared for each laboratoryparameter. Figures of changes in laboratory parameters over time will begenerated. Vital signs, ECGs, and physical exams will be tabulated andsummarized.

Additional analyses include summaries of subject demographics, baselinecharacteristics, compliance, and concurrent treatments. Concomitantmedications will be coded according to the World Health Organization(WHO) Drug Dictionary and tabulated.

The analysis of efficacy parameters was performed as follows. The pointestimate of the overall response rate will be calculated for the PPanalysis set. The corresponding 95% confidence interval also will bederived. The duration of overall response is measured from the timemeasurement criteria are met for CR or PR (whichever is first recorded)until the first date that recurrent or progressive disease isobjectively documented (taking as reference for progressive disease thesmallest measurements recorded since the treatment started).Kaplan-Meier methodology will be used to estimate event-free curves andcorresponding quantiles (including the median). Progression-freesurvival is measured from the time of first study drug administrationuntil the first date that recurrent or progressive disease isobjectively documented (taking as reference for progressive disease thesmallest measurements recorded since the treatment started).Kaplan-Meier methodology will be used to estimate the event-free curvesand corresponding quantiles (including the median).

The study scheme is a sequential cohort escalation. Each cohort consistsof six subjects. The sample size of the study is 24 to 36 subjects,depending on dose escalation into subsequent cohorts. Cohort 1 (N=6)consists of Formula (II), 100 mg QD for 28 days. Cohort 2 (N=6) consistsof Formula (II), 175 mg QD for 28 days. Cohort 3 (N=6) consists ofFormula (II), 250 mg QD for 28 days. Cohort 4 (N=6) consists of Formula(II), 350 mg QD for 28 days. Cohort 5 (N=6) consists of Formula (II),450 mg QD for 28 days. Cohort 6 (N=6) consists of Formula (II), at adose to be determined QD for 28 days. The dose level for Cohort 6 willbe determined based on the safety and efficacy of Cohorts 1 to 5, andwill not exceed 900 mg/day. Escalation will end with either the MTDcohort or three levels above full BTK occupancy, whichever is observedfirst. An additional arm of the study will explore 100 mg BID dosing.Treatment with oral Formula (II) may be continued for greater than 28days until disease progression or an unacceptable drug-related toxicityoccurs.

The inclusion criteria for the study are as follows: (1) men and women≥18 years of age with a confirmed diagnosis of CLL/SLL, which hasrelapsed after, or been refractory to, ≥2 previous treatments forCLL/SLL; however, subjects with 17p deletion are eligible if they haverelapsed after, or been refractory to, 1 prior treatment for CLL/SLL;(2) body weight ≥60 kg, (3) ECOG performance status of ≤2; (4) agreementto use contraception during the study and for 30 days after the lastdose of study drug if sexually active and able to bear children; (5)willing and able to participate in all required evaluations andprocedures in this study protocol including swallowing capsules withoutdifficulty; or (6) ability to understand the purpose and risks of thestudy and provide signed and dated informed consent and authorization touse protected health information (in accordance with national and localsubject privacy regulations).

FIG. 2 shows the median % change in ALC and SPD from baseline in theclinical study of Formula (II), plotted in comparison to the resultsreported for ibrutinib in FIG. 1A of J. C. Byrd, et al., N. Engl. J.Med. 2013, 369, 32-42. The results show that Formula (II) leads to amore rapid patient response in CLL than corresponding treatment withibrutinib. This effect is illustrated, for example, by the median %change in SPD, which achieved the same status in the present study at 7months of treatment with Formula (II) as compared to 18 months foribrutinib. The % change in SPD observed in the different cohorts (i.e.by dose and dosing regimen) is shown in FIG. 3, and in all cases showssignificant responses.

A Kaplan-Meier curve showing PFS from the clinical CLL study of Formula(II) is shown in FIG. 4. A comparison of survival curves was performedusing the Log-Rank (Mantle-Cox) test, with a p-value of 0.0206indicating that the survival curves are different. The number ofpatients at risk is shown in FIG. 5. Both FIG. 4 and FIG. 5 show theresults for Formula (II) in comparison to the results reported foribrutinib in J. C. Byrd, et al., N. Engl. J. Med. 2013, 369, 32-42. Animprovement in survival and a reduction in risk are observed in CLLpatients treated with Formula (II) in comparison to patients treatedwith ibrutinib.

Based on the data and comparisons shown in FIG. 2 to FIG. 5, the CLLstudy with Formula (II) showed that the efficacy of Formula (II) wassurprisingly superior to that of ibrutinib.

In the literature study of ibrutinib, increased disease progression wasassociated with patients with high-risk cytogenetic lesions (17p13.1deletion or 11q22.3 deletion), as shown in FIG. 3A in J. C. Byrd, etal., N. Engl. J. Med. 2013, 369, 32-42, which shows ibrutinib PFSincluding PFS broken down by genetic abnormality. The 17p and 11qdeletions are validated high-risk characteristics of CLL, and the 17pdeletion is the highest risk. In FIG. 6, the PFS is shown for Formula(II) in patients with the 17p deletion in comparison to the resultsobtained for ibrutinib in J. C. Byrd, et al., N. Engl. J. Med. 2013,369, 32-42. A p-value of 0.0696 was obtained. In FIG. 7, the number ofpatients at risk with the 17p deletion is compared. To date, no 17ppatients have progressed on Formula (II).

The adverse events observed in the clinical study in relapsed/refractoryCLL are given in Table 6. No DLTs were observed. The MTD was notreached. No treatment-related serious adverse events (SAEs) wereobserved. No prophylactic antivirals or antibiotics were needed.

The clinical study of Formula (II) thus showed other unexpectedlysuperior results compared to ibrutinib therapy. A lack of lymphocytosiswas observed in the study. Furthermore, only grade 1 AEs were observed,and these AEs were attributable to the high BTK selectivity of Formula(II).

BTK target occupancy was measured for relapsed/refractory CLL patientswith the results shown in FIG. 8. For 200 mg QD dosing of the BTKinhibitor of Formula (II), approximately 94%-99% BTK occupancy wasobserved, with superior 24 hour coverage and less inter-patientvariability also observed. For 420 mg and 840 mg QD of the BTK inhibitoribrutinib, 80%-90% BTK occupancy was observed, with more inter-patientvariability and capped occupancy. These results indicate that the BTKinhibitor of Formula (II) achieves superior BTK occupancy in CLLpatients than ibrutinib.

The effects of Formula (II) on cell subset percentages were alsoevaluated using flow cytometry analysis of peripheral blood, with theresults shown in FIG. 9, FIG. 10, FIG. 11, FIG. 12, FIG. 13, and FIG.14. PBMC samples from CLL patient samples drawn prior to (predose) andafter 28 days of dosing with Formula (II) were compared for potentialchanges in cell subsets. PBMCs were stained with monoclonal antibodiesconjugated to fluorescent tags (fluorochromes) to identify cell subsetsvia flow cytometry. Non-viable cells were excluded from the analysisusing the dye 7-aminoactinomycin D (7-AAD). To produce the metric ofpercent change, the following steps were taken. First, each cell subsetwas defined by hierarchical flow cytometry gating. Then, the change infrequency (between day 1 and day 28) was calculated for each cellsubset. MDSC subsets were measured as a % of all myeloid cells. T cellsubsets were measured as a % of all CD3⁺ cells, and NK cells weremeasured as a % of all live CD45⁺ cells. In FIG. 9 and FIG. 10, theresults show the % change in MDSC (monocytic) level over 28 days versus% ALC change at cycle 1 day 28 (C1D28) and at cycle 2 day 28 (C2D28). Acycle is 28 days. A trend is observed wherein patients with decreasingALC % had increasing MDSC (monocytic) %. This may include patients whohad quickly resolving lymphocytosis and those with no initiallymphocytosis. This provides evidence that treatment with Formula (II)mobilizes MDSCs and thus affects the CLL tumor microenvironment inmarrow and lymph nodes, which is an unexpected indication of superiorefficacy. In FIG. 11 and FIG. 12, the results show the % change in NKcell level over 28 days versus % ALC change, measured at C1D28 or C2D28,and similar trends are observed wherein patients with decreasing ALC %had increasing NK cell %. This may include patients who had quicklyresolving lymphocytosis and those having no initial lymphocytosis. Theeffects in FIG. 9 to FIG. 12 are observed in multiple cohorts, at dosesincluding 100 mg BID, 200 mg QD, and 400 mg QD. In FIG. 13 and FIG. 14,the effects on NK cells and MDSC cells are compared to a number of othermarkers versus % change in ALC at C1D28 and C2D28. These other markersinclude CD4+ T cells, CD8+ T cells, CD4⁺/CD8+ T cell ratio, NK-T cells,PD-1+CD4+ T cells, and PD-1+CD8+ T cells. The effects on NK cells andMDSC cells are observed to be much more pronounced than on any of theseother markers.

These results suggest that after Formula (II) administration, the CLLmicroenvironment undergoes a change wherein NK cells and monocytic MDSCsubsets increase in frequency in the peripheral blood in patients withfalling ALC counts, an important clinical parameter in CLL. The NK cellincrease may reflect an overall increase in cytolytic activity againstB-CLL resulting in the ALC % to drop. The increase in MDSC % in theblood may be due to a movement of these cells out of the lymph nodes,spleen, and bone marrow, which are all possible sites of CLLproliferation. Fewer MDSCs at the CLL proliferation centers would likelyresult in a reduced immunosuppressive microenvironment leading to anincrease in cell-mediated immunity against the tumor, decreased tumorproliferation, and eventually lower ALC % in the circulation.

Overall, Formula (II) shows superior efficacy as measured by ALC thanfirst generation BTK inhibitors such as ibrutinib, or PI3K-δ inhibitorssuch as idelalisib. Formula (II) has better target occupancy and betterpharmacokinetic and metabolic parameters than ibrutinib, leading toimproved B cell apoptosis. Furthermore, unlike treatment with ibrutiniband PI3K-δ inhibitors, treatment with Formula (II) does not affect NKcell function. Finally, treatment with Formula (II) leads to a CLL tumormicroenvironmental effect by excluding MDSC cells from the marrow andlymph nodes and reducing their number.

Example 3—Effects of BTK Inhibitors on Thrombosis

Clinical studies have shown that targeting the BCR signaling pathway byinhibiting BTK produces significant clinical benefit (J. C. Byrd, etal., N. Engl. J. Med. 2013, 369, 32-42; M. L. Wang, et al., N. Engl. J.Med. 2013, 369, 507-16). However, in these studies, bleeding has beenreported in up to 50% of ibrutinib-treated patients. Most bleedingevents were of grade 1-2 (spontaneous bruising or petechiae) but, in 5%of patients, they were of grade 3 or higher after trauma. These resultsare reflected in the prescribing information for ibrutinib, wherebleeding events of any grade, including bruising and petechiae, werereported in approximately half of patients treated with ibrutinib(IMBRUVICA package insert and prescribing information, revised July2014, U.S. Food and Drug Administration).

Constitutive or aberrant activation of the BCR signaling cascade hasbeen implicated in the propagation and maintenance of a variety of Bcell malignancies. Small molecule inhibitors of BTK, a protein early inthis cascade and specifically expressed in B cells, have emerged as anew class of targeted agents. There are several BTK inhibitors,including CC-292 and ibrutinib (PCI-32765), in clinical development.CC-292 refers to(N-(3-((5-fluoro-2-((4-(2-methoxyethoxy)phenyl)amino)pyrimidin-4-yl)amino)phenyl)acrylamide,or a pharmaceutically acceptable salt thereof, including a hydrochloridesalt or besylate salt thereof. Importantly, early stage clinical trialshave found ibrutinib to be particularly active in chronic lymphocyticleukemia (CLL) and mantle cell lymphoma (MCL), suggesting that thisclass of inhibitors may play a significant role in various types ofcancers (Aalipour and Advani, Br. J. Haematol. 2013, 163, 436-43).However, their effects are not limited to leukemia or lymphomas asplatelets also rely on the Tec kinases family members BTK and Tec forsignal transduction in response to various thrombogenic stimuli (Oda, etal., Blood 2000, 95(5), 1663-70; Atkinson, et al. Blood 2003, 102(10),3592-99). In fact, both Tec and BTK play an important role in theregulation of phospholipase Cγ2 (PLCγ2) downstream of GPVI in humanplatelets. In addition, BTK is activated and undergoes tyrosinephosphorylation upon challenge of the platelet thrombin receptor, whichrequires the engagement of αIIb(3 integrin and PI3K activity (Laffargue,et al., FEBS Lett. 1999, 443(1), 66-70). It has also been implicated inGPIbα-dependent thrombus stability at sites of vascular injury (Liu, etal., Blood 2006, 108(8), 2596-603). Thus, BTK and Tec are involved inseveral processes important in supporting the formation of a stablehemostatic plug, which is critical for preventing significant blood lossin response to vascular injury. Hence, the effects of the BTK inhibitorof Formula (II) and ibrutinib were evaluated on human platelet-mediatedthrombosis by utilizing the in vivo human thrombus formation in the VWFHA1 mice model described in Chen, et al. Nat. Biotechnol. 2008, 26(1),114-19.

Administration of anesthesia, insertion of venous and arterialcatheters, fluorescent labeling and administration of human platelets(5×10⁸/ml), and surgical preparation of the cremaster muscle in micehave been previously described (Chen, et al., Nat Biotechnol. 2008,26(1), 114-19). Injury to the vessel wall of arterioles (˜40-65 mmdiameter) was performed using a pulsed nitrogen dye laser (440 nm,Photonic Instruments) applied through a 20× water-immersion Olympusobjective (LUMPlanFl, 0.5 numerical aperture (NA)) of a Zeiss Axiotechvario microscope. Human platelet and wall interactions were visualizedby fluorescence microscopy using a system equipped with a YokogawaCSU-22 spinning disk confocal scanner, iXON EM camera, and 488 nm and561 nm laser lines to detect BCECF-labeled and rhodamine-labeledplatelets, respectively (Revolution XD, Andor Technology). The extent ofthrombus formation was assessed for 2 minutes after injury and the area(μm²) of coverage determined (Image IQ, Andor Technology). For theFormula (II), CC-292, ibrutinib inhibition studies, the BTK inhibitorswere added to purified human platelets for 30 minutes beforeadministration.

The in vivo thrombus effects of the BTK inhibitors, Formula (II),CC-292, and ibrutinib, were evaluated on human platelet-mediatedthrombosis by utilizing the in vivo human thrombus formation in the VWFHA1 mice model, which has been previously described (Chen, et al., NatBiotechnol. 2008, 26(1), 114-19). Purified human platelets werepreincubated with various concentrations of the BTK inhibitors (0.1 μM,0.5 μM, or 1 μM) or DMSO and then administered to VWF HA1 mice, followedby laser-induced thrombus formation. The BTK inhibitor-treated humanplatelets were fluorescently labeled and infused continuously through acatheter inserted into the femoral artery. Their behavior in response tolaser-induced vascular injury was monitored in real time usingtwo-channel confocal intravital microscopy (Furie and Furie, J. Clin.Invest. 2005, 115(12), 2255-62).

The objective of this study was to evaluate in vivo thrombus formationin the presence of BTK inhibitors. In vivo testing of novel antiplateletagents requires informative biomarkers. By utilizing a genetic modifiedmouse von Willebrand factor (VWFR1326H) model that supports human butnot mouse platelet-mediated thrombosis, we evaluated the effects ofFormula (II), CC-292, and ibrutinib on thrombus formation. These resultsshow that Formula (II) had no significant effect on humanplatelet-mediated thrombus formation while ibrutinib was able to limitthis process, resulting in a reduction in maximal thrombus size by 61%compared with control. CC-292 showed an effect similar to ibrutinib.These results, which show reduced thrombus formation for ibrutinib atphysiologically relevant concentrations, may provide some mechanisticbackground for the Grade≥3 bleeding events (e.g., subdural hematoma,gastrointestinal bleeding, hematuria and postprocedural hemorrhage) thathave been reported in ≤6% of patients treated with ibrutinib.

GPVI platelet aggregation was measured for Formula (II) and ibrutinib.Blood was obtained from untreated humans, and platelets were purifiedfrom plasma-rich protein by centrifugation. Cells were resuspended to afinal concentration of 350,000/μL in buffer containing 145 mmol/L NaCl,10 mmol/L HEPES, 0.5 mmol/L Na₂HPO₄, 5 mmol/L KCl, 2 mmol/L MgCl₂, 1mmol/L CaCl₂, and 0.1% glucose, at pH 7.4. Stock solutions of Convulxin(CVX) GPVI were prepared on the day of experimentation and added toplatelet suspensions 5 minutes (37° C., 1200 rpm) before the inductionof aggregation. Aggregation was assessed with a ChronologLumi-Aggregometer (model 540 VS; Chronolog, Havertown, Pa.) andpermitted to proceed for 6 minutes after the addition of agonist. Theresults are reported as maximum percent change in light transmittancefrom baseline with platelet buffer used as a reference. The results areshown in FIG. 16.

In FIG. 17, the results of CVX-induced (250 ng/mL) human plateletaggregation results before and 15 minutes after administration of theBTK inhibitors to 6 healthy individuals are shown.

The results depicted in FIG. 16 and FIG. 17 indicate that the BTKinhibitor ibrutinib significantly inhibits GPVI platelet aggregation,while the BTK inhibitor of Formula (II) does not, further illustratingthe surprising benefits of the latter compound.
